Installing Child-Restraint
Systems
Accident statistics reveal that a child is
safer in the rear seat. The front passenger's
seat is clearly the worst choice for any
child under 12, and with rear-facing child-
restraint systems it is clearly unsafe due to
air bags.
Some child-restraint systems now come
with tethers and therefore must be
installed on the seats that take tethers to
be effective. In your Mazda, tethered
child-restraint systems can only be
accommodated in the two positions on the
rear seat.
Even if your vehicle is equipped with
front passenger seat weight sensors (page
2-44), which automatically deactivates the
front passenger air bag, a rear seat is the
safest place for a child of any age or size.
Some child-restraint systems also employ
specially designed LATCH attachments;
refer to“LATCH Child-Restraint
Systems”(page 2-35).
WARNING
Tethered Child-Restraint Systems Work
Only on Tether-Equipped Rear Seats:
Installation of a tether equipped
child-restraint system in the front
passenger's seat defeats the safety
design of the system and will result in
an increased chance of serious injury
if the child-restraint system goes
forward without benefit of being
tethered.
Place tether equipped child-restraint
systems where there are tether
anchors.
qRear Seat Child-Restraint System
Installation
Follow these instructions when using a
child-restraint system, unless you are
attaching a LATCH-equipped child-
restraint system to the rear LATCH lower
anchors. Refer to“LATCH Child-
Restraint Systems”(page 2-35).
NOTE
Follow the child-restraint system
manufacturer's instructions carefully. If you
are not sure whether you have a LATCH
system or tether, check in the child-restraint
system manufacturer's instructions and follow
them accordingly. Depending on the type of
child-restraint system, it may use LATCH
system instead of seat belts or if the belt goes
across the child's chest, may recommend
against using automatic locking mode.
1. Secure the child-restraint system with
the lap portion of the lap/shoulder belt.
See the manufacturer's instructions on
the child-restraint system for belt
routing instructions.
2. To get the retractor into the automatic
locking mode, pull the shoulder belt
portion of the seat belt until the entire
length of the belt is out of the retractor.

Winter Driving
lCarry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask an Authorized Mazda Dealer to
perform the following precautions:
lHave the proper ratio of antifreeze in
the radiator.
Refer to Engine Coolant on page 8-14.
lInspect the battery and its cables. Cold
reduces battery capacity.
lInspect the ignition system for damage
and loose connections.
lFor improved engine starting
performance the next time you start the
engine after only driving the vehicle a
short distance, turn off the engine after
1 or more of the variable red zone
lamps in the tachometer have turned
off.
In addition, it is recommended that
short trips be avoided to ensure that the
engine reaches operating temperature
before turning off the engine.
lUse washer fluid made with
antifreeze―but do not use engine
coolant antifreeze for washer fluid
(page 8-17).
lDo not use the parking brake in
freezing weather as it may freeze.
Instead, shift to P with an automatic
transmission and to 1 or R with a
manual transmission. Block the rear
wheels.
lDo not apply excessive force to a
window scraper when removing ice or
frozen snow on the mirror glass and
windshield.
lNever use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
qSnow Tires
Use snow tires on all four wheels
Do not go faster than 120 km/h (75 mph)
while driving with snow tires. Inflate
snow tires 30 kPa (0.3 kgf/cm
2, 4.3 psi)
more than recommended on the tire
pressure label (rear door on the driver's
side), but never more than the maximum
cold-tire pressure shown on the tires.
Your vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
WARNING
Use only the same size and type tires
(snow, radial, or non-radial) on all four
wheels:
Using tires different in size or type is
dangerous. Your vehicle's handling
could be greatly affected and result
in an accident.
CAUTION
Check local regulations before using
studded tires.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system may
not function correctly when using tires with
steel wire reinforcement in the sidewalls (page
5-33).

ØThe DSC may not operate correctly
unless the following are observed:
ØUse tires of the correct size
specified for your Mazda on all
four wheels.
ØUse tires of the same
manufacturer, brand and tread
pattern on all four wheels.
ØDo not mix worn tires.
ØThe DSC may not operate correctly
when tire chains are used or a
temporary spare tire is installed
because the tire diameter changes.
ØIf repair or replacement of the
steering or other surrounding
equipment is necessary, have it
done at an Authorized Mazda
Dealer. If the center position of the
steering deviates, the DSC may not
operate correctly because there is
a sensor in the steering which
detects driving conditions.

CAUTION
ØEach tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer
on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation
pressure label, you should determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS) that illuminates a low tire pressure telltale when one
or more of your tires is significantly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle's
handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it
is the driver's responsibility to maintain correct tire pressure, even if under-
inflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
ØYour vehicle has also been equipped with a TPMS malfunction indicator to
indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for approximately
one minute and then remain continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
ØTo avoid false readings, the system samples for a little while before indicating a
problem. As a result it will not instantaneously register a rapid tire deflation or
blow out.
NOTE
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

CAUTION
ØWhen using the temporary spare
tire, driving stability may decrease
compared to when using only the
conventional tire.
Drive carefully.
ØTo avoid damage to the temporary
spare tire or to the vehicle, observe
the following precautions:
ØDo not exceed 80 km/h (50
mph).
ØAvoid driving over obstacles.
Also, do not drive through an
automatic car wash. This tire's
diameter is smaller than a
conventional tire's, so the
ground clearance is reduced
about 25 mm (1 in).
ØDo not use a tire chain on this
tire because it won't fit
properly.
ØDo not use your temporary
spare tire on any other vehicle;
it has been designed only for
your Mazda.
ØUse only one temporary spare
tire on your vehicle at the same
time.
(With limited slip differential)
When using the temporary spare tire
on the rear axle, replace it with a
standard tire as soon as possible. The
size difference between the spare and
the standard tire will cause the
limited slip differential to
malfunction.
NOTE
(With Tire Pressure Monitoring System)
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used (page 5-31).
Instant Mobility System
(IMS) Emergency Flat
Tire Repair Kit
The IMS emergency flat tire repair kit
included with your Mazda is for a
temporary repair of a slightly damaged
flat tire resulting from running over nails
or similar sharp objects on the road
surface.
NOTE
Your vehicle is not equipped with a spare tire.
In the event of a flat tire, use the emergency
flat tire repair kit to repair the tire temporarily.
When doing the repair, refer to the instructions
included in the emergency flat tire repair kit.

Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:
Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor
braking; leading to loss of control.
Use all radial, all bias-belted, or all
bias-type tires.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for your Mazda (page 10-6)
is dangerous. It could seriously affect
ride, handling, ground clearance, tire
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for your
Mazda.
qTire Inflation Pressure
WARNING
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of
tires is dangerous. Adverse handling
or unexpected tire failure could result
in a serious accident.

CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to
rear, not from side to side. Tire
performance will be reduced if
rotated from side to side.
CAUTION
Limited-Slip Differential system;
don't use the following:
ØTires not of the designated size
ØTires of different sizes or types at
the same time
ØTires not sufficiently inflated
If these instructions aren't followed,
the rotation of the left and right
wheels will be different and will thus
apply a constant load on the limited-
slip differential.
This will cause a malfunction.
qReplacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
CAUTION
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged.NOTE
(With Tire Pressure Monitoring System)lWhen tires with steel wire reinforcement in
the sidewalls are used, the system may not
function correctly even with a genuine
wheel.
Refer to System Error Activation on page
5-33.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-33.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

Worn tread
You should replace it before the band is
across the entire tread.
NOTE
Tires degrade over time, even when they are
not being used on the road. It is recommended
that tires generally be replaced when they are
6 years or older. Heat caused by hot climates
or frequent high loading conditions can
accelerate the aging process. You should
replace the spare tire when you replace the
other road tires due to the aging of the spare
tire. Regarding the manufacturing week and

qTemporary Spare Tire
Your Mazda is not equipped with a spare
tire. If you require a spare tire, consult an
Authorized Mazda Dealer.
Inspect the temporary spare tire at least
monthly to make sure it's properly inflated
and stored.
NOTE
The temporary spare tire condition gradually
deteriorates even if it has not been used.
The temporary spare tire is easier to
handle because of its construction which
is lighter and smaller than a conventional
tire. This tire should be used only for an
emergency and only for a short distance.
Use the temporary spare tire only until the
conventional tire is repaired, which should
be as soon as possible.
Maintain its pressure at 420 kPa (4.2
kgf/cm
2or bar, 60 psi).
CAUTION
ØDo not use your temporary spare
tire rim with a snow tire or a
conventional tire. Neither will
properly fit and could damage
both tire and rim.
ØThe temporary spare tire has a
tread life of less than 5,000 km
(3,000 miles). The tread life may
be shorter depending on driving
conditions.
ØThe temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator
appears, replace the tire with the
same type of temporary spare
(page 8-25).NOTE
Tires degrade over time, even when they are
not being used on the road. It is recommended
that tires generally be replaced when they are
6 years or older. Heat caused by hot climates
or frequent high loading conditions can
accelerate the aging process. You should
